JAs39E- Question regarding F414 engine thrust values

[HopfenTorpedo]

I would like to ask for clarification regarding the engine thrust values of the JAS39E in War Thunder.

The aircraft is equipped with the F414-GE-39E(RM16) engine. In game, the engine is currently shown with approximately 6060kgf dry thrust and 9490kgf afterburner thrust.

However, multiple publicly avaiable manufacturer sources list the F414-GE-39E as being rated at 98kn\22,000Ibf maximum thrust. Examples include:
-Saab official Gripen E product page

• GE Aerospace press releases regarding the F414-GE-39E
• Airforce Technolegy project description

I understand that theses figures may refer to static rated thrust values and that War Thunder uses installed or in fight performance modeling. My question is therefore not intended as bug report, but as a request for clarification:

Is the reduced thrust in game based on specific installed-thrust or operational data, or is it a balancing or gamelplay decison?

If there is publicly available information explaning why the in-game thrust values differ from the commonly cited 98kn rating, I would appreciate any clarification.

I’ll quote myself from the DEV server discussion for the JAS39E:

@Necronomica

The in-game engines (all of them) also have less thrust than the numbers mentioned in all the specifications due to something called “channel loss”. When an engine is tested it’s on a testbench and get 100% of the air it needs to run, when installed in an aircraft the engine get less air due to the airflow being restricted by the intakes and things like that. So the DEV’s usually take away a percentage of thrust but i can’t remember the exact number.

That thread is however locked now due to the update being out, you can join the discussion on the JAS39E here in this thread instead:

For lack of better thread here I am with general discussion of JAS 39E/F Gripen platform (including Gripen NG). Performance, armament, in game bugs, etc. All in one place [Gripen-E-01-scaled] Gripen related suggestions: Other Gripen related threads:

All the reports for the JAS39E are compiled there as well and it’s a good place to ask for sources and/or clarification :)
